22 Claims.

This invention relates to a machineto apply bands to bundles.

My principal object is to provide a machine that will supply a predetermined length of band material for a bundle, and after the band is wrapped around the bundle in the form of a loop, in response to a single movement of the operator, will join two portions of the band together making a fiat joint in the loop itself, then sever the main supply of the band material therefrom, and automatically present a said predetermined length of the band material to wrap the next bundle with. Another object is to provide such a machine to do this wrapping with a band made of material that presents a uniformly good appearance, that is strong, with the minimum use Of-labor and time; and, when embodying one form of joining means, does not involve any eX- pense for adhesive or staples. A further object is to make it possible for the operator to simply pull out some eXtra band material in addition to the predetermined length from the supply whenever the size of the bundle so requires.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative arrangement of parts such as is disclosed by the drawings and specification. The nature of the invention is such as to render it susceptible to various changes and. modifications, and, therefore, I am not to be limited to said disclosure; but am entitled to all such changes therefrom as fall within the scope of my claims.

are represented by the numerals I and 2 which are tied together by spacers. 3 secured by screws` 4. Between therearportions of the side frames is located aY supply-,roll 5 of tape made of paper or other` suitable material either plain or printed. This` roll of tape is located llaterally between approximately semi-circular plates-6 and I which are adjustably carried by clips 8 on said spacerst. To facilitate the adjustment of these plates each one is provided with two lat erally movable handles II connecting with plates 6. and 'I projecting through side frames I and2. In orderv to provide an unbroken surface on the plates 6 vand Inext `to the roll 5fthe metal of the platesis cut andbent as shown at 6a and la to form ,a detachable. connectionA With vthe handles 'I'I. Itwill be. noted that the handles aregraduated to indicate the propersetting for the width of tape being used. The roll 5.0i tape rests on rolls 9 which are journaled in the side frames I and 2. A cover, 5l is provided over the tape roll andtape feeding part of the mechanism shown hinged at 59. StoprGIl retains it in open position.

, The band or strip` oftape I0 is drawn from supply roll 5 through tape guides II,V and I2 by means of feed rollsI3 and I4. Guides Il and I2, shown as made of sheet metal bent U-shaped in cross section with the closed ends of the Us toward the inner surfaces of the side frames, are adjustably mounted yby means of friction spring clips I4A riveted to them and supported and frictionally located on two spacers 3. The guides II and I2 extend forwardly past rotatable feed rolls I3 and I4 to within a small clearance of knife 2 I. To facilitate the adjustment of guides II-and I2 graduated handles 11a are prof vided similar to those shown and described for adjustment of plates `I5 and 1 and similarly mounted. l

The drive feed roll I4 is carried on a shaft I5 preferably journaled in ball bearings I5A, the outer races of which are mounted in fixed position on the side frames I and 2. The drive feed roll I4 is preferably provided with a rubber surface for frictional driving contact with the tape I0. Feed roll I3 is carried on a shaft I6 preferably journaled in ball bearings |6A, the outer races of which are mounted on side frames I and 2 in vertical slots I1 and I8 so as to be movable vertically. The ball bearings IBA are pressed vertically downward by suitable springs I9 so the tape will be nipped between rolls I3 and I4 with -sumcient force to feed the tape but capable of yielding sufiiciently to permit the operator to raise roll I3 away from roll |4`enough to insert the tape when threading the machine. Said springs I9 are so formed to provide a stop portion |9a and a bendISb. Said bends |917 force said ball bearings I6a` downwardly when the said rolls I3 and I4 are in contact, as shown in Figure 1 of the drawings. When said rolls are separated to insert band material said bends IQb hold them separated by forcing ball bearings I 6a upwardly against said stop I 9a.

Drive feed roll I4 on its `shaft I5 is rotated preferably by gear teeth 22 cut into the shaft I5 in mesh with gear 23 rotatably mounted on fixed spacer 24. Also rotatably mounted on spacer rod 24 beside gear 23 is sprocket 25 on the hub of which are cut ratchet teeth 26. Sprocket 25 and gear 23 are located laterally between the shoulder 26A of spa-cer 24 and boss 21 of side frame I. Gear 23 isrotated by pawl 28 mounted on stud 29 fixed to gear 23 pressed into engagement with ratchet teeth 26 of sprocket 25 by ratchet spring 30.

Sprocket 25 is rotated by chain 3| which is pulled by tension spring 32 which is anchored to spacer rod 33 fixed to the side frames I and 2. Chain 3| extends from spring 32 part Way around sprocket 25 downwardly to the vupper end of a rod 62 which is the upper rod of a turnbuckle 63, the lower rod 64 of which is pivotably attached by pin 61 to a slide 65 mounted on a lever 34 shown pivoted on a floor bracket 34A at a pin 34B. This slide 65 may be slid along lever 34 to alter its distance from the lever fulcrum pin 34B in floor bracket 34A. Slide 65 is provided with a clamping screw 66 to holdit set in the desired position on the lever 34, and an index 66A to indicate its position relative to the scale 66B is provided on the slide 65. Scale 66B is numbered preferably to indicate the length of tape feed in inches resulting from its position.

Lever 34 is connected to and operated by a pin 1| projecting from a pedallever 12 opposite a boss 13 engaging a slot 14 in lever 34. Lever 12 is fulcrumed in floor bracket 15 at pin 16. Lever 12 is formed into a foot pedal at 58 at one end. This double lever arrangement ,is used to increase the angular movement of lever 34, carrying said slide 65 in response to-a given amount of movement applied to pedal 58. 0f course, this yobject could be attained by other means, such as a single lever, in which event the 'operating force would be applied directlytothe lever carrying the slide 65.

To present tape I0 at a point for wrapping around a bundle it is fed through guides and I2 by feed rolls I3 and I4 thence between and beyond fixed cutting knife 2| and swinging cutting knife 2| A.Vv Fixed cutting knife 2| is located above the path of the tape and extends transversely of said path with its cutting edge in the plane of its surface farther from the feed rolls I3 and I4. Knife 2| is shown attached by screws 35 to cross frame 36 which in turn is attached to side frames I and 2 by screws 31.

Swinging knife 2IA is located below the path lof the tape being fastened to swinging knife holder 38 by screws 39. Swinging knife 2IA has its cutting Iedge in the plane of its surface nearest to the feed rolls I3 and I4 to cooperate with the cutting 'edge of the fixed knife 2|. Swinging knife holder 38 is pivoted on stud 40 threaded into cross frame 36. The swinging knife holder is provided with a spring 4| to hold the cutting edge side of the swinging knife 2IA `=close against the cutting edge side of the fixed knife 2|. Swinging knife 2IA is provided with an upwardly projecting portion 42 extending from the end of the knife 2 IA at a point between the path of the tape I8 and the fulcrum pin 40. This projection 42 extends upwardly far enough to overlap knife 2| even when knife 2IA is at its lowest position, thus preventing swinging knife 2IA from being forced into interference with fixed knife 2| by the action of the spring 4|. Said spring 4| is attached at one end to the swinging knife holder 38 by screws 43 tapped into the side of the holder 38, and at its other end it engages a slot in holder 38. The middle portion of spring 4| presses against the outer surface of screw 40.

The end of the swinging knife holder 38 furthest removed from the knife is formed as shown in Figure 3 to engage and be operated by the projecting end of pin 44 when pin 44 approaches the bottom of its stroke. The different positions of said pin 44 during the cutting operation are indicated by dot and dash lines in said Figure 3.

Tape I0 is fed between the fixed 4and swinging cutting knives preferably to the extent needed to give the length of tape necessary to reach around the bundle being banded and to overlap on itself as at IUa at the tape crimping device or stapling device, later described.

The tape crimping device consists of two pairs of hardened and polished steel crimping dies, each pair comprising one fixed die 45 and one movable die 45a. The fixed dies are located above the path of the tape and are recessed into cross frame 36 and secured therein by upsetting the metal of cross frame 36 around them. The construction of these dies including their ser rations 45h in the contacting surfaces is shown in large scale view in Figure 5 of the drawings.

The movable dies 45a are located below the path of the tape and are recessed into equalizer 46 and secured thereto by upsetting the metal of the equalizer 46 around them. Equalizer 46 is semi-circular in shape to match a similarly shaped recess in a lcrimping lever 41. Crimping lever 41 is pivoted on axle 48 carried in holes in the dependent sides of cross frame 36. Attached to crimping lever 41 near its crimping die end and extending downward from it is spring 48A with its'lower end secured to side frame 2. At 69 is an open ended slot in side frame 36 through which the tape is fed and 'from which the completed band is removed. The end of crimping lever 41 opposite from the crimping die end is forked and carries on an axle 49 the four-sided cam member 5I). Recessed into cross frame 36 immediately above cam member 50 is steel plate 50A and rubber disk 50B located so as to take the reaction of cam 50. Pivoted on pawl 573 spring pressed by spring 54 against the ratchet notches cut in the edge of cammember 50.

The end of lever 5| opposite from the cam end carries projecting pin 44 in a hole drilled through it. Also carried by this pin 44 is the clevis 55 into which is screwed rod 5B supplied with turnbuckle 18 connected in turn with rod 19. The lower end of rod 19 is looped around stud 80 which is screwed into strap 8|. Strap 8| is attached by screws 82 to lever 34.

As previously stated the rear end of lever 34 is fulcrumed on floor bracket 34A. The longitudinal center line of lever 34 is approximately horizontal and is located vertically below sprocket 25 in the plane through the middle of the width of the sprocket 25. through chain 3I normallyl holds lever 34 up against pedal lever stop 6|.

Surrounding the three sides of the cross frame 36 other than the feed mechanism side is shelf 68 located with its upper surface just a trifle below the lower edge of slot 69 in cross frame 36. The' tape I8 is fed across this shelf 68 and the bundle to be banded is placed upon the tape I0.

The operator passes the tape around the bundle and introduces the end of the tape into the crimping mechanism by the help of the deflector 10 which is attached to cross frame 36 by screws 35.

Having described an illustrative construction of the mechanism embodying my invention the sequence and manner of operation will now be described.

To put the machine into operation cover 51 is printed side is down if printed tape is used sov as to cause the printed side. of the band to be visible when itsurrounds the bundle. The roll of tape is next put in place against the rolls 9 and located laterally midway between side frames I and 2 by slidably adjusting plates 6 and 1 and their attached clips 8 frictionally engaging the spacers 3 by means of handles 11.

Guides II and I2 and their attached spring friction clips i4A are slidably adjusted on spacers 3, by means of handles 11A, to guide tape I0 midway of the side frames I and 2 to line up with roll 5. Roll I3 is pushed downward into operating position to allow its spring I9 to press it against roll I4.

Next slide 65 is adjusted on lever 34 so that its index is opposite the number on the scale on lever 34 that indicates the number of inches of tape desired for the band to be made, and

it is clamped in this position by clamp screw 66.'.

To cut the tape I0 back to a point opposite knives 2| and 2|a, so that a correct start may be made, the pedal 58 is depressed by the operators foot from its normal or upmost position to cause the swinging knife 2IA to cut olf the small end Ib of the tape which in threading up had been inserted slightly beyond the near edg of shelf 66.

Spring 32 acting' from depressing pedal 58 because pedal lever 12 carrying pin 1I is activated thereby. Pin 1I engaging slot 14 in lever 34 in turn depresses lever 34. Attached to lever 34 by screws 82 is strap 8| carrying stud 80 around which is looped the lower end of rod 19. As lever 34 is depressed rod 19 follows carrying turnbuckle 18, into the upper end of which is screwed the lower. end of rod 56. As rod 56 drops it carries with it clevis 55 which is screwed onto itsupper end. Clevis 5511s pivotab-ly connected to lever 5I by means of pin 44 projecting into the path of the swinging knife holder 38. As clevis`55 drops pin 44 strikes swinging knife'holder 38 near the end of its stroke and causes swinging knife 2IA to raise past fixed knife 2| and cut the tape.

'Ihe operator now removes her foot from pedal 58 thus permitting spring 32 to contract in length pulling with it chain 3|. The movement of chain 3| rotates sprocket 25 carrying ratchet teeth 26 on its hub.A Pawl 28 engaging ratchet teeth 26 and pivoted on stud 29 in turn rotates gear 23 to which stud 29 is secured. Gear 23 meshing with teeth 22 cut into shaft I5 of drive feed roll I4, causes vfeed roll I4 to rotate and deliver the required length of banding material across shelf 68.

The machine is now ready for use.

The operator places a bundle on the tape, picks up the end of the tape, passes it around the bundle and inserts the end of the tape between the deflector 10 andthe cross frame 36 between the two pairs of crimping dies and 45a about an inch or slightly more than the length of the crimping dies.

Pedal 58 is now depressed carrying with it pedal 12 and, by means of pin 1|, lever 34. As previously described, lever 34 thru rods 19 and 56, clevis 55 and pin 44 rotates lever 5|.` As lever 5I swings it carries attached to it stud 52 supporting pawl 53. Pawl 53 in turn engages ratchet teeth cut in cam and causes it to turn.

Cam 58 is pivoted on pin 49 carried by crimping lever 41. to crimping lever 41 holds cam 50 against steel platev 50A. Steel plate 50A is backed up by a rubber disk 58B which acts as a compression spring. As one of the high spots on cam 56 is brought into contact with plate 56A by the rotation of cam 5I) the cam center is forced away from plate` 50A carrying its end of crimping lever 41. with it. This forces the opposite end of lever 415 upward carrying with it equalizer 46- and the movable dies 45a. The two thicknesses of ther brand material are thus squeezed between the fixed and movable dies. The dies are soshaped that the libres of one thickness of band` material are forced into such intimate contact with the bres of the other banding material is used, thus acting as a safety device to avoid development of excessive pressure at the dies with resulting weakening of the joint and to avoid excessive strain with permanent distortion of the. parts.

It will be observed` that the parts are so de-v This motion of swinging knife 2IA results` The tension spring 48A attached signed and related that the crimping dies 45 and 45A are separated when pedal 58 is held in normal position at the top of its stroke by spring 32, and are forced tightly together approximately at the middle of its stroke andare again widely separated at the end or completion of its stroke in one direction. Of course, this result could be attained by using a cam with a different number of lobes than the number shown and changing the angle of oscillation of lever 5| to maintain it at a little more than 360 degrees divided by the number of lobes n the cam.

When lever l is rotated by depressing pedal.

58, as described above, pin 44, carried by lever 5| strikes moving knife holder 38 near the end of the stroke of said pin and moves said holder 38 downwardly to the end of its stroke thus forcing the opposite end of holder 38 upwardly, thereby carrying moving knife 2IA past fixed knife 2| and separating the band B so formed from the roll of banding material.

Holding her foot on pedal 58 to keep the crimping dies separated the operator removes the bundle with its band on it from the machine by sliding it sidewise on the shelf 68 while the band slides out of the slot 69.

Removing her ioot now `from pedal 58 the same length of band material is again fed across table 68 ready for the next bundle to be placed on it.

In Figure 9 of the drawings I show the movable part of a well known stapling device S which is used in place of said crimping dies, being pivoted at 85 to said table 68, and operated while in an inverted position, as shown. Said shelf 68 is provided with an opening 68a, immediately above which is an anvil 86 secured by screws 81 to said table 68. Said lever 41 when operated as previously described actuates a plunger 88 of said stapling device S opposite said opening 68a to thereby drive a staple 90 through the overlapping portions Illa of said band material I0.

Should more than the predetermined length of band material l0 be needed the operator may` pull out the extra material needed because pawl 28 will click over ratchet teeth 26 permitting the feed rolls I3 and I4 to turn even though sprocket 25 remains stationary.
